nm400 material inventory will continue in the short term

Pipeline steel plate API 5L Gr.B, NM400 material, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and NM400 material heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported NM400 material to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

TMCP process is an indispensable technology for our production of low alloy high strength wide and NM400 material thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy NM400 material and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, NM400 material.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent NM400 material products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the NM400 material technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
